I have an unsolved puzzle in my "Recent Games" list. When I click on "Retry?" I get the message: "Error: This puzzle was initiated by another user. You can only play puzzles that you yourself have initiated. Click here to initate a new puzzle."

The "Retry?" entry in the "Recent Games" table shows that I initiated the game 964 minutes ago. That's 16 hours ago. It is now 4:02pm (or 16:00 hours). This means that, according to the site, I tried to start the puzzle at midnight. I was asleep at midnight. No one was on my computer.

Why does this show up in my game list? How do I get it removed? If it IS my game, why can't I play it?
